Product Specification

-
APG stocks the H3X360, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 360 mm (14.173 in), a cross section of 3 mm (0.118 in), and an outside diameter of 366 mm (14.41 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. It resists hydraulic fluids, water, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or strong acids call for a different compound.

You will find this material specified across fluid power, hydraulic and pneumatic systems, and automotive.

Stocked as H3X360 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
